      u = {}
      		 
      u._id = ObjectId()
      		 
      db.u.drop()
      		 
      db.u.insert(u)
      		 
      doc = db.u.findOne({ _id: u._id }) // { "_id" : ObjectId("50f847b777c54f68d526c7a0") }
      		 
      Object.defineProperty(doc, 'works', { value: true, enumerable: true }) // { "_id" : ObjectId("50f847b777c54f68d526c7a0"), "works" : true }
      		 
      db.u.remove()
      		 
      db.u.insert(doc)
      		 
      db.u.findOne({ _id: doc._id }) // { "_id" : ObjectId("50f847b777c54f68d526c7a0") }
      		 
      print(doc.works) // undefined <== expected `true`

      Note that enumerable properties added to an object not returned from a query ARE saved (correct behavior).
